ConstraintLayout 链上下文菜单在 Android Studio 中不再可见

Question

Using Android Studio 3.4 Canary 9 and 10 ConstraintLayout 2.0.0.alpha3

I am having an issue with constraint layout in the bleeding edge build of Android Studio 3.4 canary 9. Basically, when you click on a view in constraint layout, say on a chain element, you should be able to see small icons appear that allow you to perform certain actions on the views.

As you can see, under each view are 3 buttons that allow you to change the chain settings. However, this is what I get in my layout editor on 3.4.C09 when clicking on an element in a chain:

Did they get disabled or moved elsewhere? Is this a bug? I have looked everywhere in the IDE without any luck, tried zooming in / zooming out, changing the theme, invalidating caches/restart, clean rebuild etc.

Thank you for any help provided!

UPDATE

Now you should see Circle Chain mode option in right-click menu in Android Studio 3.6.

According to the official response, this function has been removed in AS3.4. But there seems to be no alternative. I have reported this problem to Goole and you can track here .

For now, you can add app:layout_constraintHorizontal_chainStyle attr in xml manually. And after that Cycle chain mode options will appeare in the right-click menu.

Answer 2

It is now available in attributes under layout_constraints . ( AS 3.5 )
